STK6712BMK4
From these conditions and expressions (12), (13) and (14):
t1 = 0.183 ms
t2 = 3.670 ms
t3 = 0.147 ms
Referring to Figs. 8 and 9, each value for Vst and Vdf is determined by expression (10) as follows :

This is only one example, and because convection and other air movements around the HIC will not match mathematical
modelling verification with an actual model is essential.
Motor hold noise countermeasures
The STK6712BMK4 executes constant current chopping outside the audible range. During motor hold the current hold
is outside the range of audible frequencies, but for motors of sizes 30 to 40 mm square (when seen from the shaft
direction) with inductance of about 15 mH, there are cases where the output noise is converted to low-frequency noise.
In this case, addition of the following components will essentially eliminate such audible noise.
